Mars rovers
A Mars rover is a remote-controlled motor vehicle designed to travel on the surface of Mars. Unlike stationary landers, rovers have major advantages: they can examine more territory, be directed to interesting features, and advance knowledge of remote robotic vehicle control. As of recent years, six successful Mars rovers have operated on the planet's surface, with NASA's Curiosity and Perseverance currently active. Rovers matter because they search for evidence of ancient life and habitability, study Mars' geology and climate, and pave the way for future human exploration. This scientific work helps us understand whether Mars could have supported life and prepare for eventual human missions to the Red Planet.

Rovers have several advantages over stationary landers: they examine more territory, they can be directed to interesting features, they can place themselves in sunny positions to weather winter months, and they can advance the knowledge of how to perform very remote robotic vehicle control.”
